Designed for keen home gardeners with medium to large lawns, the Kensington Petrol Garden Mower is the ultimate cartridge machine in the Allett Homeowner Range. It is one of our most popular cylinder mowers and takes all the cartridges in the Allett range allowing for a range of lawn-care tasks using just one machine. 

The Kensington 20 has a number of special features giving it an unbeatable cutting performance. The spring tine comb attached to the Kensington lifts the grass prior to cutting to ensure an even cut, and a zinc plated steel front roller and heavy steel rear roller help produce those beautiful, classic stripes that are the hallmark of an Allett lawn.

Equipped with a six-bladed precision cutting cylinder delivering 79 cuts per metre, the Allett Kensington 20 has a 20”(51cm) cut and is supplied with 122cc GX120 Honda petrol engine. It also features an infinitely variable micro cutting height adjustment from ¼ to 1 ¼ inch (6mm-32mm).

For enhanced lawn care, a range of optional additional cartridges can be fitted in place of the standard cutting unit. These include; the 10 bladed cutting cylinder, Aerator, Lawn Brush, Dethatcher, Scarifier and a Verticut cartridge.

  • Double Section Rear Roller

    The Allett Kensington 20 features a robust double-section steel rear roller with differential, enabling smooth, effortless turns without damaging turf. This design enhances durability, traction, and control while producing sharp, professional stripes and a flawless lawn finish.

  • Interchangeable Cartridges

    The Allett Kensington 20 works with six interchangeable lawn care cartridges, letting you quickly switch from mowing to tasks like scarifying, aerating, dethatching, or brushing. This flexibility transforms it into a full lawn care system, offering far more than a mower alone.

  • Height of cut 6-32mm

    The Allett Kensington 20 includes a micrometric height-of-cut adjuster, offering a precise range between 6mm and 32mm. This fine-tuned control allows you to tailor the mowing height to suit lawn conditions, ensuring accuracy and delivering a consistently clean, professional finish.

  • Fitted Grass Rake

    The Allett Kensington 20 is fitted with a spring tine grass rake positioned in front of the cutting cylinder. This feature lifts lateral grasses and clears debris before the blades cut, improving precision and encouraging a healthier, more upright lawn with a superior finish.

  • User Friendly Design

    Equipped with a self-propelled drive, the Allett Kensington 20 reduces effort for the operator, while folding handlebars and three adjustable handle height positions ensure comfort and convenience. A large 70L grassbox adds efficiency, making operation and storage simple.

  • Precision Cutting

    The Kensington 20 comes equipped with a 6-blade Quick Cartridge™ cylinder, engineered for high-quality, clean cuts that promote a healthier lawn. With 79 cuts per metre, the mower delivers a scissor-like cut that avoids tearing or bruising the grass — ideal for formal lawns where finish quality matters.
